Nowadays, the discussion about the inharmony between the local effect of relativity and the non-local effect of quantum mechanics raised by quantum entanglement has become one of the most difficult problems in physics. By taking a course called Bilingual Physics with Multimedia last semester, we have some new ideas about independent and explorative study. Inspired by the concept of education, we decided to study quantum entanglement and its application from a freshman's view. This essay mainly talks about exploring the history of quantum entanglement, the basic principles and the experimental facilities of quantum teleportation, as well as the latest scientific development on it. At last, we conclude that the exploration of science is endless and we also come up with some deep thoughts about the coming era of quantum information.
